Genes affected

PYGO2 (HGNC:30257): (pygopus family PHD finger 2) Predicted to enable several functions, including chromatin binding activity; histone acetyltransferase regulator activity; and histone binding activity. Predicted to be involved in kidney development and spermatid nucleus differentiation. Predicted to act upstream of or within several processes, including animal organ development; positive regulation of chromatin binding activity; and regulation of histone H3-K4 methylation. Part of beta-catenin-TCF complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.1213G>A (p.D405N) alteration is located in exon 3 (coding exon 3) of the PYGO2 gene. This alteration results from a G to A substitution at nucleotide position 1213, causing the aspartic acid (D) at amino acid position 405 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
